What version of Firefox are you on? Curious because the other night you mentioned using an add-on for Firefox that is no longer needed to do whatever the addon was/is doing (sorry, memory escapes me right now what that was, but it was related to your back button malfunctioning on your home page (by which I assume you mean your website home page, not your DW).

And what version of Windows or else any Linux-type thing are you using with Firefox on it? Again, just curious.

(You shouldn't need the places add-on anymore, either - that goes back many versions.)

(Also, could be a bug with DW mistakenly maintaining log-in state after clearing Firefox cache/history; been through that with DW not too long ago myself.)
